No, I have 12 instances each loaded with , apart from the strings which have 6 voices.
You must use jBridge to do this!!!!! With jBridge you can load more because jBridge loads those players outside the memory of Overture.
Sorry, while writing you mentioned ARIA and I was talking PLAY (EWQL). But I think the answer is still valid. Overture has a memory limit of 3,x Gb (32 bits limit) and with more RAM jBridge loads it all "on top" or something like this.
